OPTICAL WATER LEVEL SENSING
Attach one to four optical water level sensors and you can detect the rising or falling water levels in such applications as: water level in your sump, a low-water level in your ATO reservoir, a full skimmate waste container, or many other possibilities.

DETECT LEAKS AND STRAY WATER
Plug in up to four leak detection probes and know you have a problem BEFORE it becomes a REAL problem!

POWER ACCESSORIES LIKE PMUP AND SOLENOID VALVES
Provide an external 24V power source to the FMM and the DC24 power connector on the FMM can switch on and off devices like our PMUP, Solenoid Valve, or your own

OPEN THE DOOR TO FUTURE POSSIBILITIES
The FMM was designed such that it will be able to morph into other roles as possibilities open up – either directly from us – or from third parties.

WORKS WITH ALL APEX MODELS!
The FMM works with the Apex (2016), Apex Classic, Apex Lite, and Apex Jr. Systems.

MIX AND MATCH SENSORS AND ACCESSORIES TO GET JUST THE FUNCTIONS YOU NEED

The FMM has four ports where you can plug in various sensors and accessories (all sold separately). The best part is that they do not need to all be of the same type. This means if you want to have a flow sensor in ports 1 and 2 and then a leak detection probe in ports 3 and 4 – NO PROBLEM! Want a flow sensor for your return pump, an optical sensor for emergency sump level detection, and two leak detection probes, NO PROBLEM! Just plug them in and the FMM will automatically sense which type of sensor you have in each port.

FLOW SENSORS

Return pump
Measuring the flow of your aquarium’s main return pump is an incredibly useful piece of information. The key benefit would be to have the Apex notify you the instant the flow stops for any reason — usually the result of a failed or faulty pump. Furthermore, an indication of a reduced flow rate could be used to determine that the pump or the lines are dirty or are becoming clogged with algae, debris, animals, or the growth of organisms inside your plumbing.

Auxiliary pumps on reactors and the like
This is a very handy application for the FMM. Place a flow sensor on a device like a carbon/gfo reactor and it serves many purposes. First off, you will know if your pump is not on or is faulty. Next, you can easily fine-tune the flow into the reactor by watching the dashboard tile on your Apex. Finally, you can know when the reactor is becoming clogged with detritus or possibly channeling has occurred by an alert on your Apex or by monitoring your dashboard.

Put a flow sensor inline to your device, plug it in to the FMM, and see exactly the flow rate of the water (any aquarium fluid really) going through that sensor. The industrial-grade flow sensors work use either a turbine or paddle-wheel mechanism (depending on the model) to measure the flow.

FMK – Fluid Monitoring Kit
Get the FMM along with two 1/2″ flow sensors, one 1″ flow sensor, and a bunch of fittings all in one package. Buying the FMK instead of getting the components separately will save you some money.

OPTICAL WATER-LEVEL SENSORS

There are many useful purposes for water-level sensors on an aquarium. They can help you build an auto-top-off, monitor the levels in your supplement containers, even help automate saltwater mixing containers. Traditionally float switches have been the most commonly used types of these devices, however they are prone to all kinds of failure. On the other hand, the solid-state, optically-controlled sensors used with the FMM are much more reliable and dependable.

These optical sensors work by using an LED emitters and receptor in clear enclosure such that when it becomes wet, the light bends and no longer completes the circuit.

Easy to use
Of course you could always add water-level sensors to your Apex – but it was more complicated than most users could handle. Now, with the FMM and these optical water-level sensors, you just plug them in! No wire-stripping, no breakout box necessary!

LEAK DETECTION

In addition to flow monitoring and level-detection, the FMM can be used for leak detection. Simply plug in up to four of our new, super-sensitive leak detection probes and place them where you want that oh-so-important protection for your floors, and your marriage!

DC24 ACCESSORY PORT BUILT-IN!

The FMM has another trick up it’s sleeve. In addition to the four sensor ports, the FMM also has a DC24 accessory port and a power supply input. This can be used to add another controllable outlet to your set up. So, if you do want make your own ATO and attach our available PMUP or Solenoid Valve you can do so. Simply add our 36W 24V DC power supply.
